I have noticed that for the last week or so when I try to turn traction or stability off or launch control on nothing happens. The light does not appear on the dash or rpd to indicate any of these systems are on/off.

I will mention that I got a flat tire last week and I still have my donut on the car. I noticed that the traction and all stopped after this...but I am not sure if they are being disabled because of the spare.
If I start the car and the tpms light is flashing and I press the traction button it will sometimes turn it off.

I am at a loss with this and I wanted to know if anyone has had similar issues. I also wouldn't completely rule out an issue with my trifecta tune.......

Anyone, help???

 

It is because you have your donut on. The one TPMS on the flat is reading 0 so it refuses to turn off the traction systems. Ask me how I know hahaha.

If you can afford it you should get some Michelin Pilot Super Sports, those tires grip hard.

 

Thanks, I figured thats what it was. I am getting a brand new stock conti for $40 because of my tire warranty I bought with my car. I have a set of kdw2s on some msr wheels too
